Hi.
I have Huawei P9 with bootloader unlocked and firmware version: 8.0.0.046 (0OHZ).
First i update to
EVA-AL10b399Sp17a /Android 7 (this Firmware is required for the Update to Oreo)
then i update to
EVA-AL10C00B540 (8.0.0.540) /Android 8 Oreo
I believe I have not correctly rebranding from EVA-L09 to EVA-AL10 then firmware version is 8.0.0.046 (0OHZ) and not 8.0.0.540
Then i installed TWRP for Oreo (This TWRP is made by @Pretoriano80 for Honor 9 Lite)
Now the phone no longer enters recovery and does not start .. It restarts in loop remaining on the "your device has been unlocked and can't be trusted" screen.
Help me please

Hi everyone,
I am having trouble unlocking the bootloader for my Realme 7 5G phone (RMX2111 AU).
The specific issue is that following installation of the unlock tool, opening it leads to immediate crashing. The Stock ROM is Android 11, not Android 10. I thought if I tried to downgrade to the latter, the bug might not exist to crash the unlock tool app.
In trying to downgrade (from within Realme's Stock Recovery) I got the message "Installation failed - The installed version is lower than current."
If anyone has advice to either stop the unlock tool from crashing, or a way for me to downgrade from Android 11 to Android 10 in the hopes the unlock tool would then work normally, I would be grateful!
Thanks for any help
Hello everyone. I've been trying to no avail for at least 7 hours.
I once updated to Android 10 and my touchscreen started working funny and I've not been able to downgrade to Android 9.
I've already unlocked the bootloader and Bootloader Mode states "flashinig_unlocked".
But I can only flash Android 10 roms via fastboot flash. Everytime I want to flash for example preloader.bin or others, I get the error "(bootloader) validation image failed" on almost all images but the system.img_sparsechunk files and PGPT file.
Can someone PLEEEEASE give me a hint or hand? I've already relocked and re unlocked the bootloader.
I use Rescue and Smart Assistant to recover the phone after a failed Android 9 flash but it auto downloads Android 10 FW. I replaced the files for the Android 9 files and the process fails. I really don't know what else to do.
RSD Lite doesn't recognize my phone, the same as SPFlashTool
Thanks a lot!
HI, everybody here's my problem i've flashed a european UI3.0 x3 sz with an official realme indian Android 11 UI2.0 firmware and now i'm stuck :
1) no update via google play (no more certified google protect)
2) no more access to fastboot to re -flash the device via oppo software or any ohter software
I think the only solution is to get an official ozip file because only recovery mode is available
I tried with the only ozip file available on realme but i get this error message : cannot update with an older version, im' currently with android 11 UI.20 and the firmware available is android 10 ui1.0
thanx for your help
